Abstract

The invention relates to an electric connector comprising an inductance coil, an iron core and an iron core seat. The inductance coil is formed by repeatedly coiling a long ribbon flat conductor for at least one cycle and is provided with a through hole in the center for inserting the iron core, the iron core is inserted in the through hole of the inductance coil; the inductance coil is arranged in the iron core seat by the iron core; and both tail ends of the inductance coil extend out of the iron core seat to be connected with a peripheral circuit. The electric connector can effectively reduce the self size, thereby satisfying the design requirements of the current electrical appliances for lightness, thinness, shortness and smallness.

Description

Inductor and on inductance coil
Technical field
The present invention relates to a kind of inductor and on inductance coil.
Background technology
Inductor is one of passive component that often uses in the electric product, and in pursuing light, thin, short, the little effort of electric equipment products, it but is an insoluble problem that the volume of desire reduced inductance device is taken into account its opering characteristic of electric apparatus simultaneously always.For example, though dwindled its dc resistance of volume of inductor and but increased.
As shown in Figure 1, it is the structural representation of an existing inductor 10, it comprises an iron core 20, an inductance coil 30 and an iron core base 40, described inductance coil 30 makes and is wound in from top to bottom with copper cash that the mode of iron core 20 outer surfaces forms, and then being arranged at the inside of described iron core base 40, two ends 32 of described inductance coil 30 can stretch out so that connect peripheral circuit in described iron core base 40.Because inductance coil 30 copper cash that uses is located at iron core 20 outer surfaces as circular cross-section and with winding method, therefore the length of described iron core 20 need adapt to the number of turns that inductance coil 30 is reeled, the length L of the iron core base 40 that this kind mode is required is longer, is difficult to satisfy light, thin, short, the little designing requirement of present electric equipment products.
Summary of the invention
In view of above content, be necessary to provide a kind of inductor with smaller length structure.
Also be necessary to provide a kind of inductance coil that is applied on the above-mentioned inductor.
A kind of inductor, comprise an inductance coil, an iron core and an iron core base, described inductance coil is formed by at least one circle of the banded overlapping coiling of strap of a strip, and a through hole that is used to insert described iron core is left at its center, described iron core inserts in the through hole of described inductance coil, described inductance coil is arranged at the inside of described iron core base by described iron core, and two ends of described inductance coil stretch out to connect peripheral circuit in described iron core base.
A kind of inductance coil, it is formed by at least one circle of the overlapping coiling of a strap, and the through hole that is used to insert an iron core is left at its center.
Compare prior art, the inductance coil of described inductor is to be formed by at least one circle of the overlapping coiling of a strap, so can reduce the length of described iron core base, is adapted to light, thin, short, the little designing requirement of present electric equipment products.
Description of drawings
Below in conjunction with accompanying drawing and better embodiment the present invention is described in further detail:
Fig. 1 is the structural representation of existing a kind of inductor.
Fig. 2 is the structural representation of the better embodiment of inductor of the present invention.
Fig. 3 is the structural representation of the middle inductance coil of Fig. 2.
Embodiment
Please refer to Fig. 2, the better embodiment of inductor 100 of the present invention comprises an iron core 200, an inductance coil 300 and an iron core base 400.
Please continue with reference to figure 3, described inductance coil 300 by one equably coating at least one circle of the banded overlapping coiling of strap (as copper) of strip of insulating barrier form (being six circles in the present embodiment), and a through hole that is used to insert described iron core 200 is left at its center.During assembling, described iron core 200 is inserted in the through hole of described inductance coil 300, and then the inside that is arranged at described iron core base 400 gets final product, two ends 320 of described inductance coil 300 can stretch out so that connect peripheral circuit in described iron core base 400.
Inductance coil 300 in the inductor 100 of the present invention is owing to adopt the mode of the overlapping coiling of the banded strap of strip to design, so it is much smaller that the length M of its employed iron core base 400 is compared the length L of iron core base 40 of prior art among Fig. 1, thereby satisfied light, thin, short, the little designing requirement of present electric equipment products.
Secondly, according to existing theory as can be known, (Direct Current Resistor, computing formula DCR) is dc resistance: electric conductor resistance value=electric conductor length/(electric conductor sectional area * specific conductance).Because the sectional area of described inductance coil 300 is greater than the sectional area of described inductance coil 30, therefore under all identical prerequisite of electric conductor length and specific conductance, the dc resistance of inductor 100 of the present invention is less than the dc resistance of the inductor 10 of Fig. 1 prior art, proportional because of energy loss (PowerLoss) and dc resistance again, so the energy loss of inductor 100 of the present invention is less than the energy loss of the inductor 10 of Fig. 1 prior art, the efficient of inductor 100 promptly of the present invention will be higher than the efficient of the inductor 10 of Fig. 1 prior art.
In addition, because the inductance coil 300 in the inductor 100 of the present invention is to adopt the mode of the overlapping coiling of the banded strap of strip to design, and a layer insulating in described strap coating, for reducing eddy current loss (Eddy Current Loss), can reduce the thickness (promptly reducing sectional area) of described strap as required, with further reduction eddy current loss.
